Finally, the hanging plate structure further includes a transfer unit. In conjunction with the circuit board, working processes such as wet processes are performed.
Furthermore, the jig base and the hanging plate structure of the conventional circuit board clamping device are joined by welding. However, when joining by welding, there is a relatively large structural tolerance, which can cause distortion after clamping the circuit board, which can also affect the accuracy of subsequent processes and reduce the acceptance rate of the product There is.

  Therefore, it has been necessary to devise an improvement method for how the clamping device of the circuit board process maintains the upright state of the circuit board when the circuit board is clamped and the processing process proceeds smoothly.
